Delta Sharing lists tables but says "access to resource is forbidden" when reading table contents

[Meagan]

I am using Power BI Desktop to connect to Unity Catalog using Delta Sharing. When I connect, I enter my endpoint, enter my bearer token, browse the catalog and can see my tables. But when I try to preview or load a table, I get the error "access to resource is forbidden". 

I know the endpoint and bearer token are correct, since I can list the tables that I should be able to see. It's like there is a storage permissions issue, but I'm not sure what that would be. I'd appreciate any advice on things to try.

It turned out we had to allow my IP address on the storage account used by Unity Catalog. I guess i wasn't expecting to need that for Delta Sharing, but that indeed did fix the problem.
